Windows Media Player is a native multimedia player that is available in all versions of Windows that Microsoft supports. While Microsoft did create special editions for use in the European Union and some other regions that come without it by default, it is fair to say that the player is available on the vast majority of Windows systems.

Windows Media Player supports only select media formats by default. It supports audio formats such as mp3, wav, or wmv, and a selection of video formats as well.

The multimedia player refuses to play any format that it does not support; that is different from players such as VLC Media Player or AIMP that play a gazillion formats out of the box.

WMP Tag Plus plugin for Windows Media Player

WMP Tag Plus is an extension for Windows Media Player that adds support for several new formats to the multimedia player.

Support in this context means that Windows Media Player integrate files with the new extensions into its libraries and supports tagging. Playback support is not added, however and needs to be added through other means.

The plugin for Windows Media Player adds support for the following extensions after installation: ape, fla, flac, m4a, m4p, mpc, oga, ogg, and wv.

As far as supported formats are concerned, support is added for the following: Monkey's Audio, FLAC, Musepack, MPEG-4, Vorbis, and WavPack. All formats come with read, write and tag support.

The WMP Tag Plus options launch automatically on first start of Windows Media Player after installation and you will notice that Windows Media Player refreshes the libraries on first start as well thanks to support for new file formats.

You can open the options at any later point in time as well in the following way:

  • Select Tools > Plugins > Options from the main menu bar of Windows Media Player.
  • Switch to the Background category on the Plug-ins page.
  • Select WMP Tag Plus and then Properties.

The plugin detects if extensions have native support already, for instance through installation of codec packs, and won't interfere with the integration.

You can disable formats on the formats tab; the only reason you may want to do so is if you run into playback issues with a format that you can't resolve.

The Tools tab gives you an option to refresh song tags. Doing so will refresh tags of all songs and add the music to the library based on those tags. The program preserves existing tags and the developer notes that using the feature is only necessary if you added music files in formats that WMP Tag Plus adds to Windows Media Player prior to installation of the plugin or when the plugin was disabled.


WMP Tag Plus is a useful plugin for Windows users who work with Windows Media Player. The plugin extends capabilities of the media player.

Check out the developer's other Windows Media Player plugin, Windows Media Player Plus, which adds tag editing and other functionality to the player.

Now You: which media player do you use and why?

    Why not make use of the mplayer.conf?

    Huh, I have never even seen this “font cache” pane; videos play at once for me, using VLC & XP SP3.

    1. Martin said on August 1, 2010 at 3:39 pm

      Mike, in theory this should have only been displayed once to you, at the very first video that you played with VLC. The time this window is displayed depends largely on the number of fonts in your font directory.

        huh, I lucked out for a change?? Amazing!!
        Apparently VLC keeps this info through version updates, but I didn’t see this message after a fresh OS install about 8 weeks ago, & a new VLC.

      Great tip, thanks a lot Kishore.

    @Kishore, I’ll try your tips, but does this mean it will no longer show subtitles either?
    I do use subtitles, but the fontcache dialog box pops up (almost) everytime I play a file.

    Could this be related to the fonts I have installed? Or if I add/remove fonts to my system?

    I’ll try to do a fresh install also, if your tips does no work. I’ll post back here later…

    @ Javier, The trick i posted will show up subtitles too. If not,

  7. Kishore said on August 15, 2010 at 12:39 pm

    @ Javier, The trick i posted will show up subtitles too. If not,Dont worry, VLC is currently sorting out this issue and the next version will be out soon.

    No probs @ Martin !! Its my pleasure

    Try running LC with administrator privileges. That seemed to fix it for me

    I am using SMplayer 0.8.6 (64-bit) (Portable Edition) on Windows 7 x64. Even with the -nofontconfig parameter in place SMplayer still scans the fonts. Also, I have enabled normal subtitles and it is still scanning fonts before playing a video. Also, it does this every time the player opens a video after a system restart (only the fist video played).

    Does that mean that only instrumental versions of songs will be available for non-paying users?
